Which of the following best describes the energy resource used most often for heating and cooking in less developed countries?

• Bituminous coal is primarily used because of its relative abundance and high moisture content.

• Cogeneration from fuel oil systems is primarily used because it has low up-front costs.

• Biomass is the predominant fuel source because it is easily obtained locally.

• Natural gas is the most prevalent fuel source because it is readily available and produces few air pollutants.

In the majority of less developed countries, the major source of energy for domestic use is which of the following?

• oil

• coal

• biomass

• Nuclear

• geothermal

How many BTUs were consumed in the United States in 2017 by consumers that used petroleum as a fuel source?

• 28 quadrillion BTUs

• 36 quadrillion BTUs

• 62 quadrillion BTUs

• 97 quadrillion BTUs

Which of the following best describes an advantage of burning biomass rather than burning fossil fuels in developing countries?

• Biomass production requires less open space than fossil fuel extraction does, so land is available for other purposes.

• Burning biomass is associated with fewer human respiratory concerns than fossil fuels are because it does not give off sulfur oxides and nitrogen oxides.

• Biomass production is cheaper than fossil fuel extraction, making it more readily available for use.

• Burning biomass is more efficient than burning fossil fuels, providing more available energy from less of the resource.

Which of the following is a drawback to using biofuels, such as ethanol, as a fuel source?

• Ethanol-blended gasoline has higher carbon emissions than petroleum alone.

• The global demand for biofuels is continually decreasing.

• There is high energy investment in producing and processing the crops needed for ethanol production.

• Ethanol-blended gasoline increases the likelihood of freezing gas lines in winter months.

• A large glacier in a mountainous area

• A river delta in a forested region

• An area of sand dunes in a desert
